DoorKing 1815-284 AWID Proximity Reader MR-1824MC

Mid-Range AWID Proximity Card Reader w/ Metal Compensation

The DoorKing 1815-284 is a genuine AWID MR-1824MC Sentinel-Prox proximity card reader engineered specifically for direct mounting on metal surfaces. The MC version includes integrated ferrite plates behind the base that compensate for metal interference, delivering up to 16 inches of read range when mounted on a metal surface at least as large as the reader. This makes it the correct choice for metal pedestals, metal enclosures, and pole-mounted installations where the standard MR-1824 would suffer significant read range loss. Dual data output via Wiegand and RS-232 interfaces provides flexible integration with access control panels. An independent external linear regulated DC power supply is required.

Key Features

• Genuine AWID MR-1824MC Sentinel-Prox proximity reader with metal compensation for direct metal surface mounting
• Up to 16 in read range on metal surfaces at least 8 x 8 in — correct choice for metal pedestals and enclosures
• Integrated ferrite plates behind base eliminate metal interference without requiring plastic spacers
• 3-color LED and 4 kHz piezo-electric beeper provide visual and audible feedback controllable by host panel
• Self-testing and self-diagnostic functions confirm correct performance and detect power instability without controller connection
• Re-present mode prevents multiple reads from single card presentation
• Dual simultaneous output via Wiegand and RS-232 serial interface
• Compatible with all AWID 125 kHz proximity credentials including clamshell cards, keytags, and adhesive wafers
• Suitable for indoor and outdoor installation with minimum IP64-rated housing when exposed to rain or snow

Conclusion

The DoorKing 1815-284 AWID MR-1824MC is the correct proximity reader for installations where direct metal surface mounting is required. If mounting on a non-metal surface, the standard MR-1824 (1815-283) is the appropriate choice. Confirm credential compatibility with AWID 125 kHz proximity cards and verify environmental protection and power supply requirements before ordering to ensure proper system integration and long-term reliability.
